Title: Improvements in and relating to rotary pumps
IPC: F04C2/332
Filed: 1929-11-27
Abstract: 331,176. British Thomson-Houston Co., Ltd., (Assignees of King, R. E.). Nov. 27, 1928, [Convention date]. Fixed-abutment type; mounting and supporting; discharge and suction pipes and passages for pumps; starting and stopping.-A pump for a compression refrigeration machine has a rotary casing 24 which is an extension of a vertical driving shaft 26 coupled to an electric motor 15, and an inner eccentrically placed rotor 27 which is driven by the casing through a connecting vane 49. The whole unit is mounted on springs 17 inside a chamber 13, leads 16 supplying current to the motor. Refrigerant is fed to the pump by way of a pipe 19 through a port 18 and a check valve 43, Fig. 5, and passes via a supply duct 41 in the base bearing 38 to a duct 40 which leads to pump inlet ports 39. The fluid is pumped through a check valve 45, Fig. 2, to a delivery port 20 and discharged into the chamber 13 whence it flows into the intake 21 of the condenser. The condensate passes out through a float valve 22 to a pipe 23. A bye-pass valve 73, Fig. 5, allows refrigerant to pass from the intake to the delivery side until the pump reaches a predetermined speed when centrifugal force causes the valve, which is arranged eccentrically, to close a port 70, and the pump then functions normally. This prevents the motor from being heavily loaded while running at a low speed. Ribs 75 are provided on the valve. The vane 49 acts as a pump for lubricating oil 65 which is drawn through a strainer 62<a> into a conduit 60 which supplies the vane pump chamber when open to 'a port 61. During the return stroke of the vane 49 the end of the conduit 60 is moving over a port 63 and lubricant is pumped through a passage 64 to channels which feed bearings 33 and 34, and also grooves 57 and 53 to seal the end faces of the main pump chamber to prevent leakage. A slot 66 supplies lubricant to the vane seating 51.

Title: Improvements in or relating to piezoelectric crystal units
IPC: G10K11/00
Filed: 1944-06-02
Abstract: 600,300. Sound emitting and receiving apparatus. BRUSH DEVELOPMENT CO. June 2, 1944, No. 36836/46. Convention date, March 26, 1942. Divided out of 600,248. [Class 40 (iv)] [Also in Group XL (c)] A piezo-electric crystal unit comprises a crystal element having acoustic decoupling means mounted directly on some only of the faces of the crystal element, the decoupling means having an acoustic impedance which is low compared with the acoustic impedance of the crystal element. Fig. 3 shows an expander unit comprising a crystal plate having electrodes 13 on one pair of opposite faces so as to cause a useful vibration in the direction of arrows 5, and an unwanted vibration in the direction of 4. The unwanted vibration is decoupled from the surrounding medium, which may be oil, by means of sheets 14 of rubber-impregnated cork. The unit may be employed in a sub-aqueous compressional wave sender and receiver of the kind described in Specification 600,248. Fig. 4 shows a twister bimorph in which cork strips 14 are mounted on one side of opposite quadrants so as to decouple the unwanted movement from the surrounding pressure medium. For a simple clamped bender element, one side is coated (Fig. 5, not shown) while for a free bender the coatings are at the ends on one side and in the middle on the other side (Fig. 6, not shown). Fig. 7 shows an end-on row of expander crystals 11 for a directional instrument. Electrodes 12, 13 produce useful movement of faces 51, 52. Endwise movement is absorbed by spacers 14 of cork and rubber. In Fig. 9, a piezo-electric unit comprising a crystal having a thin cork layer 111 over its electroded major faces and thick pieces of cork 112 on its edges is bound by thread 113 to electric leads 116 and inserted in a perforated metal tube 122. This is enclosed in a rubber tube 127 closed by a nosepiece 124 and base 125. The rubber tube is exhausted and filled with oil by means of plug 131. For directional working, a number of such crystals arranged end to end in a long rubber tube may be used. Specifications 318,934, [CLass 40 (iv)], and 592,217 also are referred to. The Specification as open to inspection under Sect. 91 also describes a modification of the Fig. 7 arrangement in which the decoupling means are replaced by metal bellows. In Fig. 10 (Cancelled), the piezo-electric elements 68 are arranged in an inner air-filled vessel 62 in contact with a sealing diaphragm 64. The outer vessel 63 is oil filled and is sealed by a diaphragm 65. This decouples the side faces from the surrounding oil. This subject-matter does not appear in the Specification as accepted.

In a motor vehicle change-speed gear, a common, reversible, hydraulic, pneumatic or electric motor effects cross-shift and gearestablishing movements of a shift lever 12 in the usual double H, single H, or single H with one additional branch, pattern, respectively by cam means acting on a slide block 20 in a straight slot of which the lever is movable, and by crank means moving the lever along the slot. As shown, an electric motor drives a cam disc 21 through gears 16, 14, 26-29 and a crankpin 15 mounted on the gear 14, the reduction ratio between the gear 14 and the cam disc being 3/1. The cam disc has three cam segments corresponding to 1-2, 3-4 and Reverse cross-shift positions and acts on a roller follower of a cross-guided, spring-returned rod 24 fixed to the slide block 20. The crank-pin 15 is connected to the shift lever by a connecting rod 13, the crank-pin radius corresponding to gear-establishing movement from Neutral. Clock and anti-clockwise rotation of the gear 14 respectively effects up and down (and Reverse) shifts through the gears. Control (not described) of the gear and main clutch is semi- or fully automatic. The electric motor may be switched off, and the gear engaged may be indicated, by contacts or limit switches actuated by the shift lever or cams connected to the gear 14 or the cam disc. Preferably, the shift control is driven by an electric motor having a permanent magnetic field for rapid stopping by short-circuiting the armature. In Fig. 3 (not shown), a cam disc having a spiral groove including three concentric arcs of different radii is secured to the gear 14, the opposite ends of a lever respectively sliding in the groove and being connected to a crossguided rod fixed to the slide block.

Filed: 1974-08-27
Abstract: 1479370 Containers; closures; portable containers SAS ANGELO GUALA DI PIERGIACOMO E ROBERTO GUALA & C 27 Aug 1974 [31 Aug 1973] 37450/74 Headings B8T and B8D A closure device incorporating a safety seal for bottles, of the type incorporating a pierceable container for substances to be introduced into the bottle consists of two moulded plastics elements 1, 2. Element 1 has cup portion 9, 10 and a tubular portion 3 with two internal axially spaced apart annular ridges 4, 5 and a tubular portion 6, below ridges 4, 5 of smaller diameter than tubular portion 3 and closed by a rupturable base 7. Element 2 comprises a tubular portion 12 adapted to fit inside the tubular portion 3 of element 1 and having an external annular ridge 14 and a piercing tip 13 adapted to be used to tear the rupturable portion 8 connecting the base 7 to the wall 6 of element 1. The tubular portion 12 is closed at its upper end by a transverse wall 15 which projects radially beyond the portion 12 and supports a cylindrical depending collar 16. The transverse wall 15 is connected peripherally, by means of breakable radial bridge elements 17, to a cylindrical bush 18 coaxially surrounding the tubular portion 12 and provided with an internal annular ridge 19. The operation of the closure device is as follows. After having placed a substance B into element 1 and having engaged element 2 into element 1, the closure 1, 2 is placed in the neck of the bottle until the cup part 9 rests on the neck of the bottle, an axially directed force is applied to the transverse wall 15 to move ridge 14 on to ridge 5 and thus expand the tubular portion 3 to wedge the closure device 1, 2 into the neck of the bottle. Further downward movement is prevented by ridge 19 engaging the edge of cup portion 10 and prevents the rupturing of the base 7 by the tip 13. Pulling the bush 18 upwards with a twisting movement breaks the bridge elements 17 and allows removal of the bush 18. A further downward motion of element 2, until the collar 16 seats in cup portion 9, is now possible. This movement results in breakage of rupturable portion 8 by tip 13, releasing substance B into the bottle and, by taking ridge 14 past ridge 5, allows elastic contraction of the tubular portion 3 so that the closure device can be extracted from the bottle.
